Good concept, details need some work.
Fit Type: Slim Fit, Color: Grey, Size: Small
Let's start with the positives. The quality of the cloth is great, it's a heavier cotton, but feels soft and durable. The overall slim fit cut was great too. The shoulders were a tiny bit too boxy for me personally, but I didn't wash it to see if the shirt would shrink and solve that issue. The problem with this shirt is that it doesn't get the details right. It's almost like they just took a regular shirt and decided to produce it in a slim fit instead, without tweaking anything else. It's slightly too long to be left untucked, and for a cloth this heavy, it's not really something that you would really want to wear tucked in. I also find it weird that a slim fit shirt would have a box pleat on the back, since the whole point of a slim fit shirt is for a cleaner look on a trimmer guy. Finally, I like the button-down collar, but would consider hiding the buttons on the back of the collar so that you get a cleaner look. Unfortunately, these misses on the details make this shirt seem outdated. Other than the slim cut, it reminds me of something you might see from the 1990s, along with double pleated chinos. Overall, doesn't seem like a good match for a younger, more stylish demographic that might want to wear a slim fit cut. Despite the great price, I'm definitely returning this one.

Very nice winter shirt.
Fit Type: Slim Fit, Color: Blue, Size: Large
These shirts are beyond what I expected. They’re thicker than I thought but not being too heavy. They wear well and they also wash up very well in permanent press and I dry them on permanent press also. No problem with wrinkles. I just take them out of the dryer and hang them up and they look great.

Amazon Essentials Mens shirt review - Good shirt, great value.
Fit Type: Slim Fit, Color: Grey, Size: X-Large
First, this is Oxford. This is a tough fabric that looks a little like pinpoint and feels a little like flannel. That is, it does not have the sheen of a dress shirt and is not as thick and soft as flannel. It hits a nice spot in between. The fabric is soft enough and thick enough to wear casually in the heat of summer. (It is cooler than a very thin and very cheap shirt due to it's absorbancy.) The fabric appears and feels to be quality. The cut is good for me. It is tailored enough to look good tucked in and roomy enough for work and play. The seams are doubled and good quality. I did not find mid seam knots, broken threads, etc. Seams are likely very durable. The Goodthreads shirt is a little more expensive. It is a little thicker and softer. It is almost a flannel. However, the thickness and softness caused it to shrink more in the dryer. It loosened OK as I wore it, but I think after multiple washings and dryings, the Goodthreads may get a little tight. I have no concerns with the Essentials. Good shirt.

Nice shirt, great price.
Fit Type: Regular Fit, Color: White, Size: Medium
Worn it twice and I find it very comfortable. I wear it outside and casually to protect my arms and neck from the sun and find it more comfortable than a long sleeve t-shirt. The price is comparable. If I was to wear it to the office it would have to be ironed. I bought one shirt to try it and I will be buying more.
